I've been thinking about making and installing a bow protector plate, although I haven't got round to it yet.

I figured on using CAD/CAM technology to make a template - that's Cardboard Aided Design, Cardboard Aided Manufacture.

Get the shape and size right with a piece of cardboard, then cut the stainless out to the cardboard template.

New things impress my old brain but I will believe it when I see it.

Thanks.

The technique used is called photogrammetry

I wrote using a cellphone but any camera can be used just that a cellphone can run directly the software needed for it as opposed to a DSLR camera.

I do understand that (a good friend has a number of these printers and they are amazing, but as even stated in the Utube video the camera must see the object from ALL sides.

We shall see.

It must see the object from all side to get a complete 3d model, for example if you want to scan let say a cup you need a full 360 access to the cup as the software only rely on image and cannot extrapolate how is the back of the cup. Any view part not available will be missing from the model so if you have access to only half of the cup you will get a half cup. But for a bow plate the issue does not exist as back is just an empty part, see what I mean?
So provided you have scanned the surface, and you edit the created model to give it a thickness, then you have a 3d bow plate model.
Only thing is that the scanned surface must not be too shiny and must have texture so the software can "see" it, and usually a bow is shiny and all white. But by using a temporary dotted sticker on the bow it should do the trick.
I will play with it when I have some free time as it can be a funny experience

Great, please repeated back what you learn. As I envision it you would end up with a proper length and width but would not have the bend to confor to the bows shape.

Looking forward to hearing back from you.

Thanks.

It is shiny like the axe of a viking! I would be scared to be cut in half if I had to look behind me and see you coming my way
